Eagle Rock Energy Partners, L.P. Announces Crude Oil, Natural Gas
                   Liquids and Interest Rate Hedges

    HOUSTON--(BUSINESS WIRE)--Sept. 26, 2007--Eagle Rock Energy
Partners, L.P. (Nasdaq:EROC) ("Eagle Rock" or the "Partnership")
announced today it has entered into several hedging transactions to
help mitigate its future commodity price and interest rate exposure.
On Sept. 13, 2007, Eagle Rock entered into a West Texas Intermediate
(WTI) crude oil swap for 2008 on 80,000 barrels per month at a swap
price of $73.90. Eagle Rock also entered into WTI crude oil collars to
negate pre-existing out-of-the-money collars for 2008 production of
the same 80,000 barrels per month, at a cost of approximately $9.1
million. The combined impact of these two transactions was to raise
Eagle Rock's floor on those volumes by $23.90 per barrel while at the
same time raising its cap by $6.51 per barrel to its swap price of
$73.90 for 2008. In addition, the Partnership has increased its hedged
volumes on its upstream crude oil production by 25,000 barrels per
month for the years of 2009 and 2010 at swap prices of $71.25 and
$70.00, respectively.

    The Partnership also executed swap transactions on its natural gas
liquids production from its midstream assets for the fourth quarter of
2007, increasing ethane hedged volumes by 40,000 barrels per month at
$0.8338 per gallon, propane by 35,000 barrels per month at $1.2775 per
gallon, iso-butane by 8,500 barrels per month at $1.5575 per gallon
and normal-butane by 16,000 barrels per month at $1.5275 per gallon.

    In addition, on Sept. 25, 2007, Eagle Rock entered into natural
gas liquids direct swaps for 2008 and 2009 on its un-hedged ethane and
propane production volumes. The ethane swaps include 25,000 barrels
per month for 2008 at a swap price of $0.72 per gallon and 25,000
barrels per month for 2009 at a swap price of $0.6361 per gallon. The
propane swaps were entered into for 35,000 barrels per month for 2008
at a swap price of $1.19 per gallon and for 15,000 barrels per month
for 2009 at a swap price of $1.0925 per gallon.

    To mitigate its interest rate risk, on Sept. 17 and 18, 2007, the
Partnership entered into three-month Libor swaps for the period of
Oct. 1, 2007 through Dec. 31, 2010 at a weighted average swap rate of
approximately 4.66% on an additional $150 million of its outstanding
indebtedness.
